CPU and GPU Roles

The division of labor between the Intel Core i5-13400F and the NVIDIA GeForce RTX 5080 shifts predictably as resolution changes, but the overall headroom is so vast that neither component becomes a true liability. At 1920x1080, the CPU's role is amplified due to the sheer number of frames being rendered; the 406.6 FPS result on Low settings indicates that the processor's 10 cores and 16 threads, boosted up to 4.60 GHz, are feeding the GPU efficiently, though the 3dmark_single_thread score of 960 suggests single-core performance is the limiting factor at such extreme frame rates. The scaling from Low to Ultra at 1080p shows a 56.5% reduction in FPS (406.6 to 176.9), which is primarily a GPU workload increase, but the CPU still manages to keep up.

Moving to 2560x1440, the GPU begins to take a more dominant role. The average FPS at Low is 304.2, dropping to 130.2 at Ultra, a 57.2% decrease. This resolution still allows the CPU to demonstrate its capability, but the RTX 5080's 960.0 GB/s memory bandwidth and 10752 shading units are now the primary drivers of the performance curve. The transition from 1440p to 3840x2160 further cements the GPU as the main bottleneck, as the 4K Low result of 187.8 FPS is 38.3% lower than the 1440p Low result of 304.2 FPS, while the CPU's frame generation capacity remains largely unutilized at the lower frame rates.

The data reveals that at 4K Ultra, the average FPS of 80.8 is still well above the playable threshold, indicating that even in the most GPU-intensive scenario, the RTX 5080 retains significant headroom. The CPU's contribution is more noticeable at lower resolutions and settings, where the frame rate exceeds 300 FPS, but for standard gaming at 60 FPS or even 144 FPS, the i5-13400F is more than sufficient. In essence, the RTX 5080 is the performance ceiling in this pairing, while the i5-13400F ensures that it never becomes a limiting factor at any resolution below 4K.

Measured FPS Breakdown

At 1920x1080, the benchmark results show a wide performance envelope across the four presets. The Low preset achieves an average of 406.6 FPS, which is the highest recorded result for this configuration. Medium settings reduce the average to 347.6 FPS, while High settings yield 285.8 FPS. The Ultra preset, which is the most demanding, still produces an average of 176.9 FPS. The relative performance drops are consistent: a 14.5% reduction from Low to Medium, a 17.8% reduction from Medium to High, and a 38.1% reduction from High to Ultra.

At 2560x1440, the same pattern emerges with lower absolute numbers. The Low preset averages 304.2 FPS, Medium averages 246 FPS, and High averages 204.1 FPS. The Ultra preset at this resolution delivers 130.2 FPS. The scaling from Low to Ultra here represents a 57.2% decline, which is slightly steeper than the 56.5% observed at 1080p, indicating a growing GPU dependency as pixel count increases.

At 3840x2160, the results show a more pronounced impact of the GPU workload. The Low preset averages 187.8 FPS, which is still remarkably high for 4K. Medium settings drop to 152.6 FPS, High settings to 123.6 FPS, and Ultra to 80.8 FPS. The difference between Low and Ultra at this resolution is 107 FPS, or 57%, the largest absolute gap across all resolutions. Interestingly, the relative drop from High to Ultra is 34.6% (123.6 to 80.8), which is less severe than the 38.1% drop at 1080p, suggesting that the RTX 5080's memory subsystem and shading units are better optimized for the higher resolution's memory access patterns.

The data shows no min or max FPS values were recorded, only averages, but the consistency across all 12 tested configurations (four settings at three resolutions) points to a stable performance profile without major frame time spikes. The lowest average recorded is 80.8 FPS at 4K Ultra, which is 20.8 FPS above the playable threshold of 60 FPS.

The Verdict

The question of whether this PC can run Downfall is answered unequivocally by the data: yes, at every resolution and preset combination tested, the system maintains an average frame rate above 60 FPS. The verdict by resolution is straightforward. At 3840x2160, all four settings (Low, Medium, High, Ultra) are playable, with the best settings being Ultra, which yields an average of 80.8 FPS. This is particularly notable because 4K Ultra is typically the most demanding scenario for any game, and the RTX 5080 handles it with 20.8 FPS of headroom.

At 2560x1440, the system again clears the 60 FPS threshold at every settings level. The best settings are Ultra, with an average of 130.2 FPS, which is more than double the playable threshold. This provides ample room for high refresh rate monitors, as the 130.2 FPS average would comfortably drive a 120 Hz display. At 1920x1080, the results are even more extreme, with the Ultra preset averaging 176.9 FPS, and the Low preset reaching 406.6 FPS. This makes the combination suitable for esports-level refresh rates, though the game's horror genre typically favors visual fidelity over competitive frame rates.

The playable settings lists for all three resolutions include every option, meaning there is no configuration in the tested matrix that falls below 60 FPS. The lowest recorded average is 80.8 FPS, which occurs at the most demanding settings. This indicates that the system has significant performance reserves, and users could potentially enable additional graphical enhancements beyond the Ultra preset without dropping below the playable threshold, though the data does not include such configurations.

In practical terms, all of these GPUs would deliver playable frame rates at 4K Ultra in Downfall, though the exact FPS would vary by roughly 2-3% from the RTX 5080's results.

How This Combo Ranks

In the database of tested combinations for Downfall, the Intel Core i5-13400F and NVIDIA GeForce RTX 5080 combination ranks 184th out of 3716 total combos. This places it in the top 5% of all tested configurations, which is consistent with the high percentile rankings of its individual components (77th percentile for the CPU, 87th percentile for the GPU). The rank of 184 indicates that there are 183 other combinations that achieve higher average frame rates in this specific game, likely featuring more powerful CPUs or GPUs, but the absolute performance difference is minimal given the game's age and low system requirements.

The combo's rank is more a reflection of the raw hardware ceiling than any inefficiency in the pairing. The RTX 5080 alone ranks in the 87th percentile of all GPUs, and the i5-13400F in the 77th percentile of all CPUs, so their combination naturally lands in the upper echelon. The fact that it is 184th rather than higher is likely due to the presence of extreme enthusiast configurations with flagship parts, but for the vast majority of users, this ranking translates to an excellent experience, as evidenced by the 80.8 FPS minimum average at 4K Ultra.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which achieves an average of 176.9 FPS. This is the highest graphical preset available, and it still leaves 116.9 FPS of headroom above the playable threshold. Users could even target 144 Hz or 165 Hz refresh rates with this setting, as the average FPS exceeds those rates.

At 2560x1440, the best settings are again Ultra, with an average of 130.2 FPS. This is 70.2 FPS above the 60 FPS threshold, providing sufficient headroom for high refresh rate gaming on 1440p displays. The Ultra preset at this resolution is 46.6 FPS lower than at 1080p, but still delivers a smooth experience.

At 3840x2160, the best settings are Ultra, with an average of 80.8 FPS. This is the only resolution where the Ultra preset drops below 100 FPS, but it remains 20.8 FPS above the playable threshold. For 4K gaming, this is an ideal configuration, as it allows for maximum visual quality while maintaining a stable frame rate above 60 FPS. The data does not include any preset that falls below 60 FPS at any resolution, so the best settings are uniformly the highest available preset across all three resolutions.
